An Overview of Stem Cells
Overview
Stem cells are cells that have the potential to replicate themselves for
indefinite periods and to divide, producing one copy of themselves and one
cell of a different type (differentiation). In humans, stem cells have been
located in: the early stages of development after egg fertilization (around 5-
6 days); the umbilical cord and placenta; and in several adult organs.
Regardless of their source all stem cells have two general properties:
e Stem cells are capable of dividing and renewing themselves for long
periods. Unlike muscle cells, blood cells, or nerve cells — which do not
replicate themselves — stem cells can divide continuously and keep
their innate properties.
e Stem cells are undifferentiated and can give rise to multiple cell-types.
Stem cells do not have any tissue-specific structures that allow them to
perform specialized functions. They cannot carry molecules of oxygen
through the bloodstream like red blood cells or release signals to other
cells, such as permitting the body to move or speak, as nerve cells do.
Although stem cells do not have any tissue-specific structures, they
can give rise to differentiated cells, including red blood cells and nerve
cells.
Stem cells have varying abilities to differentiate into different cell-types
(see Figure 1). One type of stem cell can give rise to any other cell-type of a
given organism (for example, an embryonic stem cell). Other stem cells can
only give rise to cells of a given tissue type (for example, bone marrow can
produce blood stem cells) or only give rise to a few cell-types in a given
tissue.
Scientists are just beginning to understand the signals in a body which can
trigger cell differentiation. These signals can be created within a cell,
triggered by a cell’s genes, or by a neighboring cell that releases chemicals
to promote differentiation in other cells. Determining what these signals are
and what stem cells require to differentiate into different cell-types is a
crucial research area which must be explored in order to utilize stem cells
for therapies.
When cells differentiate, their abilities become more restricted. They often
follow only a few prescribed pathways and can lose the capacity to replicate
themselves. The ability of stem cells to replicate and remain unspecialized
until they are needed is an important area of research vital to understanding
human development.
Stem cells offer a new look at old problems and diseases such as burns and
diabetes. Although the field is relatively new, the impact of new discoveries
could profoundly change medical research and therapy. Many of these new
approaches involve the use of somatic cell nuclear transfer (sometimes
known as therapeutic cloning) to produce recipient-specific tissue by
creating embryonic stem cell lines.
This new area of research has great potential, but it is not without its
controversies. Many ethical dilemmas are produced with the creation and
destruction of human blastocysts as well as the potential to clone an entire
human being (reproductive cloning). No matter where society designates
the boundary to be for this research, or whether or not stem cells can live up
to our high expectations, a great deal can be learned through careful and
thoughtful studies.
The Potential Uses of Embryonic Stem Cells
Embryonic Stem Cells
Embryonic stem cells are derived exclusively from a fertilized egg that has
been grown in vitro for 5 to 6 days to form a blastocyst. Within a
blastocyst there is a small group of about 30 cells called the inner cell
mass, which will give rise to the hundreds of highly specialized cells
needed to make up an adult organism. Embryonic stem cells are obtained
from this inner cell mass. For research purposes, embryonic stem cells are
produced specifically from eggs that have been fertilized in vitro, or ina
laboratory and not inside a woman’s body, or in vivo. Embryonic stem cells
can come from a frozen fertilized egg or an egg which is fertilized in vitro.
Embryonic stem cells can and do differentiate into all the specialized cells
in the adult body. They could be induced to provide an unlimited source of
specific and clinically important adult cells such as bone, muscle, liver or
blood cells (See Figure 2).

Adult Stem Cells
Adult stem cells are unspecialized or undifferentiated cells found among
specialized cells in an adult tissue or organ. In some adult tissues, such as in
bone marrow, muscle, or brain tissue, discrete populations of adult stem
cells generate replacements for cells that are lost through disease, injury, or
normal wear and tear. Adult stem cells are thought to reside in an area of
each tissue where they may remain quiescent, or non-dividing, for many
years until they are activated by disease or tissue injury. Where they are
found, adult stem cells consist of a very small population of cells within
each tissue.
Some adult stem cells retain the ability to form into specialized tissues other
than the one from which they originated. For example, blood
(hematopoietic) cells have not been proven to differentiate into nerve,
skeletal muscle, cardiac muscle, or liver cells (see Figure 3). There is some
evidence that brain stem cells can differentiate into blood or skeletal muscle
cells. However, adult stem cells have a limited number of tissues they can
differentiate into and do not have the same potential as embryonic stem
cells to become any cell-type.
The environment that adult stem cells grow in has an important, but poorly
understood, effect on their fate. The relationship between the adult stem cell
environment and its ability to differentiate into other cell-types has also not
been fully explained.

Distinctions between Embryonic and Adult Stem Cells
Most importantly, adult and embryonic stem cells differ in the type of
differentiated cells they can become. While embryonic stem cells can be
induced to differentiate into any cell-type, adult stem cells cannot. Most
adult cells can only differentiate into the types of cells found in their
environment or in the particular tissue or organ where they reside.
Therefore in many vital organs, adults do not have the stem cells necessary
to regenerate damaged areas; thus scar tissue will develop instead.
Another key difference between embryonic and adult stem cells is the
volume of cells one can isolate and grow in vitro. Large numbers of
embryonic stem cells can be grown in vitro from a single blastocyst. On the
contrary, adult stem cells are rare and methods of growing them still need to
be perfected. In addition, due to their limited numbers, it is difficult to
isolate a group of adult stem cells in pure form, without having them
contaminated with differentiated cells.
Potential Uses of Stem Cells

Parkinson's Alzheimer's Burns
Spinal cord injury Stroke Heart Disease
Diabetes Osteoarthritis Infertility

Stem Cells
While stem cell research is in its infancy and many of its proposed uses are
hypothetical, the research has generated excitement among many scientists
for its potential. One of the vital components of ongoing work is
understanding the very nature of these cells; that is, to determine the
conditions necessary to maintain undifferentiated stem cells as well as
differentiating them along specific pathways. In order to truly determine
whether or not these cells can be used therapeutically, more research must
be conducted to understand the nature of the cells.
Although we are only beginning to discover what stem cells are capable of
doing, scientists have proposed several potential uses.
1. Abnormal Cell Division. Many serious medical conditions, such as
cancer and birth defects, are due to abnormal cell divisions or the
inability of cells to turn themselves on and off properly. Having a
better understanding of stem cells and their genetic and molecular
controls would yield information about diseases and reveal potential
strategies for therapies.
. Drug Testing. Stem cells could be used to test new drugs or
medications by differentiating them to the particular cell-types that the
drugs are targeting. This would offer a short-cut for scientists to sort
out chemicals that can be used to treat diseases. By testing new drugs
on stem cell lines, we could perform rapid screening of hundreds of
thousands of chemicals that now are tested by more time-consuming
processes. This could also potentially decrease the time that it takes to
get a drug to market.
. Cell-Based Therapies. Stem cells could be used for cell-based
therapies. Stem cells could be directed to differentiate to a specific
cell-type that then could be used as a renewable source of replacement
cells and tissues. In order to be useful for cell-based therapies, stem
cells must be made to:
Differentiate into desired cell-types. It is necessary for stem cell
techniques to be improved until they can consistently and efficiently
differentiate into a specific cell or type of cells without contamination
by undifferentiated or improperly differentiated cells.
Proliferate extensively and generate sufficient quantities of tissue. The
protocols for differentiating stem cells need to be refined so that large
quantities of tissue can be produced in a relatively efficient manner.
Survive in the recipient after the transplant. Scientists must determine
that the cells are healthy and viable after transplantation. They also
should establish that the stem cells are localized to the correct tissue in
the recipient.
Function appropriately for the duration of the recipient’s life. Not only
do the cells need to be localized and survive, but they must also
behave like the original cells. Currently, there is not sufficient data
showing that stem cells are functional in their new environment when
they are transplanted into organs. For cell-based therapies to be
successful, the new cells need to function correctly and interact
properly with the original tissue.
Avoid harming the patient in any way. One concern about using
undifferentiated cells or stem cells is the risk of the stem cells having
genetic abnormalities which could cause them to be cancerous or to be
rejected due to tissue immune incompatibility. Adequate testing is
necessary to make sure the cells used are healthy.
Embryonic Stem Cells
One of the most promising uses for embryonic stem cells is the study of the
complex events that occur during human development. The earliest stages
of human development have previously been difficult or impossible to
study. By using embryonic stem cells, these studies can be performed with
the goal of preventing or treating birth defects, infertility, and pregnancy
loss.
The use of embryonic stem cells can also help scientists identify how
undifferentiated cells become differentiated. Since these cells have the
ability to become any type of cell in the adult body, they have a larger
potential for medically viable tissues which can be derived and used in cell-
based therapies.

Cloning
Cloning
Somatic cell nuclear transfer (SCNT) is when the genetic material
(nucleus) of an unfertilized egg is removed and replaced with the genetic
material of a normal cell. The egg is then activated and allowed to grow.
After it is allowed to grow into a blastocyst, embryonic stem cells are
obtained from the inner cell mass. These embryonic stem cells can then be
induced to become other differentiated cell-types. (See Figure 1)
Much of the promise for embryonic stem cells lies in the potential of
deriving or creating cell lines which are specific to a person. This technique
can be used to create cell lines and study the development of different
diseases (sometimes called therapeutic cloning). For instance, by using a
skin cell from a patient suffering with Parkinson’s disease one could create
a cell line that would show the researcher how the cell progressed from a
normal to a diseased state. Not only could scientists study specific genetic
diseases, but they could also create tissues that are compatible with the
original donor.
Further, this technique can also be used to create tissues that are recipient-
specific. In organ and tissue transplantation, a great concern is the rejection
of transplanted tissue by the recipients’ immune system. If new cell lines
were created to be identical to the recipient, this would no longer be a
problem.

Reproductive Cloning is when an egg undergoes somatic cell nuclear
transfer and the resulting cell is allowed to grow to an infant that is an exact
genetic copy of the somatic cell donor. Attempts at reproductive cloning
have been error-prone and inefficient, resulting in the failure of most clones
to develop. The most famous clone, Dolly (a sheep), was only created after
multiple attempts and failures and then lived a shortened life (Wilmut et al,
1997).
Another option for creating stem cells without using egg cells has been
discovered in mice. When four specific genes are added to a normal cell
(such as a skin cell) the cell become deprogrammed, and regains its ability
to be differentiated into many different types of tissue and to divide
indefinitely. This innovative procedure has problematic aspects though; one
of the necessary genes contributes to cancer in some of the mice studied,
and genes are introduced into the skin cells by way of a retrovirus, which
may also cause adverse effects in any tissue cultures grown using this
method. However, if this procedure were ever adapted to human cells, the
issue of immune rejection of grafted tissue would be eliminated, as the stem
cells are genetically identical to the donor cells.

Case Study: Junvenile Diabetes and Stem Cell Research
Case Study: Juvenile Diabetes and Stem Cell Research
Juvenile diabetes, also known as type 1 diabetes, is essentially an
autoimmune disease where one’s own body starts attacking itself. In
juvenile diabetes the body specifically destroys a pancreas cell, the &-cell,
which produces insulin. Insulin is an important hormone that balances
blood sugar levels. Unregulated sugar levels in the blood can lead to severe
problems such as kidney failure, blindness, stroke, and even death. Patients
with juvenile diabetes are required to take multiple injections of insulin
daily or have a continuous infusion of insulin through a pump just to
survive. Also, they must constantly monitor their food intake and daily
activities.
Scientists have been working for years to find a cure and are extremely
optimistic about the potential use of stem cells to replace destroyed f-cells.
In a recently published study using mice, Harvard researchers determined
that new &-cells in the pancreas are formed through the replication of pre-
existing {§-cells, rather than adult stem cells creating new {-cells. These are
the very cells being attacked and therefore their numbers are limited. This
result means that in order to cure juvenile diabetes, scientists must rely on
another source of {-cells, such as embryonic stem cells, to generate new {-
cells.

American Stem Cell Research: Politics and Policies
Overview
In February of 1997, Dr. Ian Wilmut announced the creation of the first
cloned mammal. The report, published in the science journal Nature,
described a lamb, "Dolly," which was cloned using somatic cell nuclear
transfer (SCNT). This landmark paper and the media attention it received
created an immediate reaction from the public and politicians in
Washington, D.C. who were concerned about the potential cloning of
humans using this technique. Since Dolly’s creation, congressional leaders
have been trying to find a way to prevent human cloning and other
allegedly unethical medical procedures while still allowing medical
research to proceed unhindered.
In late 1998, the issue was further complicated by the announcement from
researchers at the University of Wisconsin-Madison, led by Dr. James
Thomson, who derived the first human embryonic stem cells from
blastocysts. This marked the beginning of a new area of medical science,
human embryonic stem cell research. With this new breakthrough, the issue
of human cloning became considerably more complex, since SCNT was
now linked to potential disease-curing research.
With each congressional session, a new crop of conflicting bills arises from
both the House and the Senate, and congressional hearings are called to
bring witnesses in to validate either side, but no resolution appears to be in
sight. Although many polls have shown that the vast majority of Americans
disapprove of research which could produce a cloned human (79% in a
2005 poll by Research! America), there is still much public debate about the
ethics of embryonic stem cell research. This debate resonates in the
Congress and generates the current stalemate where lawmakers are unable
to reach a consensus about medical research relating to embryonic stem
cells.
Pre-“Dolly” Regulation
In the 1970s, rules were developed to govern the federal funding of research
on human embryos for in vitro fertilization (IVF). The rules specified that
all federally funded research on human embryos would need to be
approved by a congressionally appointed ethics advisory board. Although
the board met once, it was dissolved in 1980 without ever federally funding
embryonic research. In 1993, this rule was rescinded, but the Dickey
Amendment, a Department of Health and Human Services (DHHS)
1996 appropriation rider, subsequently banned any federal funding of
human embryo research and each year this amendment has been attached to
the appropriation bill for the DHHS. Since that time, no federal funds have
been allowed for embryo (and therefore embryonic stem cell) research, but
private funding of research on embryos has been allowed and is completely
unregulated.
Post-“Dolly” Debate
In February of 1997 after the public announcement about “Dolly”, President
Clinton charged the National Bioethics Advisory Council (NBAC) to
study the issue of human cloning. In June of that year, NBAC released a
report which determined that reproductive cloning was immoral and
requested that a moratorium should be established until subsequent laws
prohibiting it were passed (with a sunset period of 3-5 years). The members
also suggested that the law be written so it would not interfere with
biomedical research. Taking their suggestions, President Clinton offered a
legislative proposal to bar anyone (either federally or privately funded)
from attempting to clone a human through SCNT for 5 years. President
Clinton’s proposal was announced after several bills in the House and
Senate had already been introduced (see Table 1). However, due to the fear
that Congress was acting too quickly and might bar valid research, the
majority needed to pass these bills was never attained and thus no
legislation limiting such cloning was ever successfully passed into law.

In November of 1998, after Dr. Thomson announced the creation of the first
human embryonic stem cell line, President Clinton asked NBAC to
specifically address human embryonic stem cell research, which had not
been discussed in 1997. In 1999, the NBAC recommended that federal
funding should be used to support both the research and creation of human
embryonic stem cells. They also suggested amending the ban on embryo
research (the Dickey Amendment) to allow the derivation and use of
embryonic stem cells.
However, before the results of the NBAC deliberations were announced, the
National Institutes of Health (NIH), specifically the legal council for the
DHHS, determined that federal law (the Dickey Amendment) prohibited the
use of federal funds to create human embryonic stem cell lines, but they did
believe that it was legal to fund research on already existing lines. Private
sources were never barred from deriving their own human embryonic stem
cell lines and were actively pursuing this area of research. The NIH released
guidelines for the federal funding of human embryonic stem cell research
for public comment in 1999, followed by an updated version in 2000 in the
Federal Register. Before NIH was able to grant money in response to
research proposals, a new administration (President George W. Bush) took
office and the previous rulings by the DHHS and NIH were set aside.
Meanwhile in the Senate, the Specter-Harkin bill (S.2015) was introduced
as the Stem Cell Research Act of 2000. It called for the federal funding of
the derivation and use of human embryonic stem cells from spare donated
embryos (IVF), as long as the research did not lead to "reproductive cloning
of a human being.” This marked the first of many bi-partisan bills that
Congress would see on this issue. The Specter-Harkin bill, like many future
bills, was not passed into law.
When President Bush took office, one of his first actions was to temporarily
stop all federal funding of human embryonic stem cell research (no grant
had been given) while his administration considered their actions. On
August 9, 2001, after several months of deliberation, President Bush
announced that he would allow the federal funding of the research of
human embryonic stem cells, but only those that had been derived before
the date of the announcement could be used. Thus, no new embryonic stem
cells could be created with federal funds, nor could federal funds be used to
do research on new lines create after the August 9, 2001 deadline. NIH
estimated at the time that there were as many as 60-75 cell lines available
for research. However, since that time, NIH has revised its numbers
downward. By the 2004 presidential campaign, NIH had only 22 lines
available (see insert “Effect of President Bush’s Stem Cell Policy”).
Since the President’s August 9, 2001 decision, embryonic stem cell policy
has remained unchanged. In November 2001, President Bush established
the President’s Council on Bioethics (PCB), a group of experts (similar
the NBAC), to address the issues of human cloning, embryonic stem cell
research and other bioethical issues. In Congress, new bills were introduced
in the 107th and 108th congress, and the Weldon-Stupak bill was passed in
House in 2001 and 2003 to ban all forms of cloning and the use of SCNT,
but neither passed in the Senate. Almost every year we see each political
side introduce their version of a law which would outlaw all human cloning
or only reproductive cloning and either outlaw or permit the use of
embryonic stem cells, but nothing has been signed into law.
Perhaps the most interesting part of the congressional debate is the fact that
views on the topic do not necessarily follow traditional party lines or a
person's opinion on abortion or right to life. This new debate has produced
the most unlikely bipartisan partnerships and has resulted in a deadlock in
Congress, which has sharply constrained federally funded research on
embryonic stem cells and human cloning. At the same time, the deadlock
has virtually left the privately funded research involving embryonic stem
cells and human cloning completely unregulated.
Momentum for expanding federal funding for embryonic stem cell research
began to build again as the 2004 presidential campaigns kicked into gear. In
April of 2004, 206 members of the House of Representatives (out of 435)
signed a letter to President Bush urging him to expand the current federal
policy on embryonic stem cell research to include new lines developed after
August 9, 2001. Following the House’s lead, the Senators that advocated
embryonic stem cell research also wrote a letter to President Bush with 58
signatures (out of 100). On May 10, 2004 former First Lady Nancy Reagan
publicly supported embryonic stem cell research at a fundraiser for juvenile
diabetes. Although privately she had supported the research with personal
letters to congressmen, this was her first public statement on the topic.
Nancy Reagan and the Reagan family are often thought of as icons for the
Republican Party and conservative ideals. This public acceptance led the
way for other Republicans to support the issue. One month later, President
Reagan, a victim of Alzheimers, passed away. Stem cell research was
immediately brought into the forefront as a campaign issue for the 2004
election. Senator Kerry supported the expansion of the research, while the
President Bush explained his current policy and promised to maintain the
status quo.
With the return of President Bush to office in 2005, the possibility for
changing the current federal policy seems unlikely. However, in May 2005,
the U.S. House of Representatives passed the Stem Cell Research
Enhancement Act, perhaps the most significant legislative advance in the
support of stem cell research (see Table II). Its passage was the result of an
initiative from the leaders in both parties. The bill amends the Public Health
Service Act to provide for stem cell research by stating that cells donated
from excess supplies from IVF clinics are viable for use. It stipulates that
these donations are to be made from embryos determined never to be
implanted in a woman and under informed consent without any financial
inducements. The bill goes on to say that reports of research carried out
under these guidelines should be presented each fiscal year. The Stem Cell
Research Enhancement Act needed to be passed by the U.S. Senate, and
although the Senate Majority Leader, Senator Bill Frist (R-TN) promised to
bring it forward in 2005, the vote did not occur until July 2006. As he
promised in May 2005, President Bush vetoed the bill on July 19, 2006 (the
first use of the Presidential veto by Bush) and Congress was unable to
override it.

With or without the expansion of federal funding, some states (such as
California, Massachusetts, and New Jersey) are beginning to pick up the
reins by passing their own laws related to embryonic stem cell research (see
page 15 “State Cloning Legislation”). In November 2004, Californians
(with 59% of the vote) approved Proposition 71, or the California Stem
Cell Research and Cures Initiative, which called for the creation of a
California Institute for Regenerative Medicine (CIRM) and authorized $3
billion of state funds to support the effort over the next five years. The
proposal also established the right to conduct embryonic stem cell research
in California, but prohibits reproductive cloning. President Bush’s policy
only limits federal funding, but does not make the research itself illegal
therefore the states are able to determine how they wish to regulate and
fund research using state funds. CIRM supports embryonic stem cell (and
adult stem cell) research regardless of the date the cells were generated, to
create new cell lines, and to use SCNT to create cell lines with specific
genes. This new institute is expected to attract stem cell researchers and
investors to California allowing it to corner the market on any promising
findings.
Despite the passage of Proposition 71, several obstacles have delayed its
implementation in California. A lawsuit by taxpayer groups contended that
CIRM could not sell bonds backed by taxpayer money to fund research,
because it is not under direct state control. Bond sales that would be used to
fund the institute are on hold until the lawsuit is settled. In April 2006, the
court ruled in favor of CIRM, but the case is still in appeals. Furthermore,
CIRM needed time to determine the rules for awarding grants, conducting
research, and handling patent rights before it started funding grants.
However, in April 2006 CIRM was still able to award their first round of
grants, which totaled $12.1 million, and in July 2006 California Governor
Arnold Schwarzenegger agreed to give the institute a $150 million loan to
help while litigation was pending.
Summary
The debates on stem cell research essentially started in 1997, after the first
mammal, “Dolly,” was cloned. Through the past decade, the United States
government has not been able to agree on the best policy. The Bush
Administration put into place a policy that allows some research to proceed,
but at the same time it fails to address the research that is taking place with
private and other non-federal funds. Recently, Congress finally settled their
stalemate and passed legislation to increase the number of cell lines derived
from leftover IVF eggs. Unfortunately, this was vetoed, leaving the question
of regulation of this research unresolved. Whether we should fund
embryonic stem cell research and therapeutic cloning and how to regulate
the current research done with private funds are questions U.S. lawmakers
still need to address.
Example:
Effects of President Bush's Stem Cell Policy
In an effort to appease the advocates for embryonic stem cell research, but
still stay true to his conservative base, President Bush allowed federal
funding of research on human embryonic stem cells derived on or before
August 9, 2001. At the time of the announcement, the NIH believed that
there were 60-75 lines which met the qualification for federal funding.
Since the announcement, scientists have found several problems with the
cell lines which were approved:
1. Currently there are only 22 lines available for distribution by the NIH
(the other lines were unavailable for distribution). Many of the other
cell lines were either unavailable to researchers or had contamination
problems, chromosomal abnormalities, or were unstable.
2. All the cells had been created using mouse cells; therefore, they
cannot be used in humans for fear of spreading mouse viruses in
humans. It also has been shown recently that all the lines tested
contained mouse proteins on their surface which causes them to be
rejected by the immune system in a human. This means the cells are
unlikely to ever be used for medical purposes.
3. Older cell lines are more susceptible to chromosomal abnormalities
than newer lines. So over time, the current stem cell lines will degrade
and are not medically viable.
4. Several of the lines have been difficult to grow, giving them very
limited uses.
5. Each approved cell line has the propensity to grow into only one
specific cell-type. This decreases the breadth of research opportunities
for scientists.
6. The cell lines lack genetic diversity necessary to create therapeutic
treatment for a broad number of patients
7. There is an absence of disease-specific cell lines, thereby limiting
stem cell research on genetic diseases.
Improvements in how scientists can grow the cells in vitro have made new
cell lines created in other countries and from private funding (now
numbering over 150 lines) more appealing than the lines approved for
federal funding. This discourages scientists from using the cell lines,
applying for the federal funds, or even entering the field. Most scientists,
especially new faculty and graduate students, rely heavily on public
funding during their careers.
This policy also limits the availability of subsequent discoveries to the
general public. Since private firms will own any therapies derived from
such research and may charge heavily to recoup their investments, they
have no incentives to publicly release their data.

State Cloning Legislation
State Cloning Laws
Note:The information in this section is provided to illustrate the diversity
of approaches various states are taking with regard to regulation of human
cloning and embryonic stem cell research. The brief summary is based on a
review of relevant literature and websites and should be considered
preliminary.
Overview
While the United States has not passed any federal legislation concerning
ESC research and human cloning, individual states have started passing
their own laws. Sixteen states have legislation involving human cloning.
Arkansas, California, Connecticut, Illinois, Indiana, Iowa, Maryland,
Massachusetts, Michigan, New Jersey, North Dakota, Rhode Island, South
Dakota, and Virginia have passed legislation to prohibit reproductive
cloning. Arkansas, Indiana, Michigan, North Dakota, and South Dakota
also prohibit therapeutic cloning (cloning for research). Virginia fails to
define "human being," and so it is unclear if therapeutic cloning is banned.
Arizona, Indiana, and Michigan specifically prohibit the use of state funds
for any human cloning, while Missouri prohibits public funding for
reproductive cloning only. California, Connecticut, Illinois, Iowa,
Maryland, Massachusetts, New Jersey, and Rhode Island specifically allow
therapeutic cloning. California, Connecticut, Illinois, Maryland, and New
Jersey have also gone so far as to fund such research using state money.
Twenty-six states have no legislation addressing either cloning or
embryonic stem cell research and therefore have no policy on record.
However, almost all of these states have pending legislation. Louisiana is
the only state that bans research on IVF embryos, but this does not cover
therapeutic or reproductive cloning as long as the blastocyst comes from
another source such as being created from a sperm or unfertilized egg cell.
Thus cloning is not explicitly restricted in Louisiana.
States with Bans on Research Destroying Embryos
Louisiana, Michigan, Minnesota, North Dakota, South Dakota, and
Pennsylvania.
States with Bans on Reproductive and Therapeutic Cloning (SCNT)
Arkansas, Indiana, Michigan, North Dakota, South Dakota, and Virginia
(because ‘human being’ was left undefined in the legislation)
States with Bans Only Reproductive Cloning
California, Connecticut, Illinois, lowa, Maryland, Massachusetts, New
Jersey, and Rhode Island.
States with Bans on Public Funds

Overview of World Human Cloning Policies
Overview
Note:The information in this section is provided to illustrate the diversity of approaches various
different parts of the world are taking with regard to regulation of human cloning and embryonic stem
cell research. The brief summary is based on a review of relevant literature and websites and should be
considered preliminary.
World policies on human or reproductive cloning range from complete prohibition to no policies on
record. Over 30 countries, including France, Germany, and the Russian Federation, have banned human
cloning altogether. Fifteen countries, such as Japan, the United Kingdom, and Israel, have banned
human reproductive cloning, but permit therapeutic cloning. A few countries such as Hungary and
Poland do not explicitly prohibit embryonic stem cell research or therapeutic cloning, partially because
their legislation was drafted before embryonic stem cells were first produced (1998). Many other
countries, similar to the United States, have yet to pass any official legislation concerning human
cloning allowing all types of stem cell and cloning research to occur.
In addition to countries developing their own policies, several international organizations, including the
United Nations, the Council of Europe, and the European Union, have published human cloning
policies and recommendations, which are described below. Several other organizations including the
African Union and the Arab Leagues have discussed the issue, but have yet to release a formal
declaration. Furthermore, the International Society for Stem Cell Research (ISSCR) and a group led by
Johns Hopkins Phoebe R. Berman Bioethics Institute, known as the Hinxton Group, are working to
outline principles for human embryonic stem cell international collaboration and cooperation.

World Cloning Legislature
*Some prohibit the derivation of embryonic stem cells, but do not specifically prohibit the research
using existing lines.
**Ban refers to countries which banned human cloning (both reproductive and therapeutic).
United Nations
On March 8, 2005, the United Nations General Assembly adopted the nonbinding ‘Declaration on
Human Cloning’, by which member states were called on to adopt "all measures necessary to prohibit
all forms of human cloning inasmuch as they are incompatible with human dignity and the protection of
human life." The vote was 84 in favor (including United States, Germany, and Italy), 34 against
(including United Kingdom, South Korea, and Brazil), 37 abstaining (including South Africa and Israel)
and 35 were absent. This Declaration is arguably weakened by the fact that it was not even passed by a
majority of the UN membership.
Many countries, in formal explanations of their votes, expressed disappointment that there was no
consensus on the language of the declaration and said that it was regrettable that it did not cover the
well-known differences between reproductive cloning and therapeutic cloning (somatic cell nuclear
transfer). The original mandate to the Legal Committee was to elaborate on the issue in an international
treaty against human reproductive cloning. Instead, text of the declaration blurred the line separating
reproductive and therapeutic cloning.
Council of Europe
The Council of Europe is an international organization of 46 countries in Europe, which was established
in 1949. The Council was set up to defend human rights and democracy, develop continent-wide
agreements to standardize social and legal practices and promote European interests. Membership to the
Council is open to all European democracies, which accept the principle of the rule of law and
guarantee fundamental human rights and freedoms to their citizens.
The Council of Europe has several conventions that can be applied to human embryonic stem cell
research and human cloning. The Council’s 1997 Convention on Human Rights with Regard to
Biomedicine highlights the “need to respect the human being both as an individual and as a member of
the human species.” The protocol on cloning states that “any intervention seeking to create a human
being genetically identical to another human being, whether living or dead is prohibited.” While this
specifically bans reproductive cloning it does not necessarily ban therapeutic cloning. The Council left
the interpretation of ‘human being’ to national Parliaments, allowing therapeutic cloning where it is
accepted. In several European countries without specific stem cell or cloning legislation (Bulgaria,
Croatia, Cyrus, Moldova, Romania, and San Marino) this convention is interpreted to mean that they
allow human embryonic stem cell cloning, but ban both reproductive and therapeutic cloning.
European Union
The European Union is an intergovernmental and supranational union containing 25 member states
from Europe. It was established in 1950 by six countries (Belgium, France, Germany, Italy,
Luxembourg, and the Netherlands) and dealt with economic and trade issues. It now has an additional
19 member states (Denmark, Ireland, United Kingdom, Greece, Portugal, Spain, Austria, Finland,
Sweden, Cyprus, Czech Republic, Estonia, Hungary, Latvia, Lithuania, Malta, Poland, Slovakia,
Slovenia) for a total of approximately 450 million people and deals with a wide range of issues
including health, the environment, and international peace and stability.
The European Union supports funding embryonic stem cell research (where permitted), but has banned
the funding of human cloning. There is no legal ban on therapeutic cloning, but the European Union
will not fund research using SCNT to create embryos. It allows for countries to determine within their
border what embryonic stem cell research can be funded allowing that it is carefully regulated, peer
reviewed, scientifically sound, directed towards sustainable goals, and ethically sound.

Also known as “involuntary muscle,” these muscles perform automatic
tasks such as peristalsis and blood vessel constriction. Named smooth
muscle because of smooth, rather than striated, appearance under a
microscope.
Somatic Cell
Any cell of a plant or animal other than the germ (sperm or egg) cell.
Somatic Cell Nuclear Transfer (SCNT)
When the genetic material (nucleus) of an egg is removed and replaced
with the genetic material of a normal cell.
Stem Cell
An unspecialized cell that can replicate itself for indefinite periods
through cell division and under certain conditions becomes a
specialized cell.
Therapeutic Cloning
When embryonic stem cells created by somatic cell nuclear transfer
are studied in vitro and used for cell-based therapies, but never are
implanted in a female or grown past 14 days.
Undifferentiated Cell
A primitive cell that does not have any tissue-specific structures that
allows it to perform specialized functions. It has not changed to
become a specialized cell.
Zygote
The cell (and the organism that develops from the cell) resulting from
the union of an ovum and spermatozoon (also referred to as a fertilized
ovum).
